local But = vgui.Create("DButton",frame)

function AddButtons()

	A:SetText("Does nothing")
	A.Paint = function( self, w, h )

end

Gets this error

[ERROR] lua/rekt.lua:34: attempt to index global 'A' (a nil value)
  1. DoClick - lua/rekt.lua:34
   2. unknown - lua/vgui/dlabel.lua:218

That error is because you're defining A as a local variable, which is making A only exist in the AddButtons function. You need to do

local A, B

At the top of your script, and then when defining them, just do

A = something
B = something

(That defines the local variables from before as something else)
